【摘要】:目的:通過動(dòng)態(tài)測定先天性心臟病患兒修補(bǔ)術(shù)或畸形矯正術(shù)前后血循環(huán)腦鈉肽(Brain natriuretic peptide, BNP)的變化,了解先心病患兒修補(bǔ)術(shù)或畸形矯正術(shù)對心功能的影響,從而及時(shí)掌握術(shù)后患兒心功能恢復(fù)情況,做到早期診斷、早期治療患兒心功能異常。 方法:1.采用前瞻性研究方式,以我院2010年3月至2011年3月實(shí)施全麻下經(jīng)體外循環(huán)開胸進(jìn)行小兒先心病修補(bǔ)術(shù)和畸形矯正術(shù)的患兒87例做為研究對象;同時(shí)期門診體檢的健康兒童26例為健康對照組。2.根據(jù)先心病類型,分為3個(gè)亞組,房間隔缺損組、室間隔缺損組、法洛氏四聯(lián)癥組。并對研究對象的性別、年齡、體重以及治療方法,手術(shù)名稱,術(shù)后用藥,術(shù)后住院時(shí)間進(jìn)行登記。同樣記錄對照組患兒年齡,性別,體重。3.術(shù)前BNP值采集時(shí)間為術(shù)前1天,由專人采患兒靜脈血2ml,放入EDTA抗凝管,混勻后取標(biāo)準(zhǔn)量全血進(jìn)行BNP的檢測,術(shù)后1天,2天,7天同樣由專人取患兒靜脈血2ml,放入EDTA抗凝管保存后進(jìn)行檢測,記錄數(shù)值。健康對照組兒童采集BNP時(shí)間為體檢當(dāng)天,采集方法同前。所有BNP應(yīng)用免疫熒光干式定量法進(jìn)行含量測定。4.采用SPSS13.0版統(tǒng)計(jì)軟件對資料數(shù)據(jù)進(jìn)行統(tǒng)計(jì)學(xué)分析。統(tǒng)計(jì)檢驗(yàn)均以α=0.05為檢驗(yàn)水準(zhǔn)。 結(jié)果: 1一般資料 對照組和先心病組資料年齡、體重以及各時(shí)間點(diǎn)血漿BNP數(shù)值均為非正態(tài)分布(正態(tài)性檢驗(yàn)P0.1),均用中位數(shù)(四分位間距)即M(QR)表示 1.187例先心病患兒,房間隔缺損組(1組)14例,室間隔缺損組(2組)63人,法洛氏四聯(lián)癥組(3組)10例。病例中男童總數(shù)56例,女童31例,男女比例為1.8:1;年齡2(4)歲,體重12(8.5)公斤。 1.2健康對照組患兒26例,其中男童16例,女童10例,男女比例1.6:1;年齡2.5(3)歲,體重12.5(7)公斤。 1.3對照組以及先心病組患兒不同年齡,不同性別,不同體重BNP均無差別(P0.05)。術(shù)前3組間年齡、性別、體重差異無統(tǒng)計(jì)學(xué)意義(P0.05)(Fig.1-Fig.2),對照組與先心病組之間比較,年齡、性別、體重?zé)o差異(P0.05)(Table1)。 1.4術(shù)前患兒心臟彩超左室射血分?jǐn)?shù)均50%,患兒術(shù)后住院時(shí)間5-9天,平均7天,術(shù)后常規(guī)應(yīng)用米力農(nóng)增強(qiáng)心肌收縮力最短1天,最長5天,平均2天,應(yīng)用多巴胺改善循環(huán)最短2天最長5天,平均3天,術(shù)后常規(guī)應(yīng)用地高辛、卡托普利、螺內(nèi)酯、氫氯噻嗪,藥物至出院后復(fù)查。 2統(tǒng)計(jì)分析結(jié)果 2.1先心病組術(shù)前與對照組之間BNP比較 先心病組術(shù)前BNP為10.30(40.7) pg/ml,對照組BNP為6.95(14.4)pg/ml,兩組BNP之間比較P=0.012P0.05,差異有統(tǒng)計(jì)學(xué)意義。先心病組患兒術(shù)前BNP水平高于對照組(Table2)。 2.2先心病組3組患兒術(shù)前BNP比較 術(shù)前房間隔缺損組(1組)、室間隔缺損組(2組)、法洛氏四聯(lián)癥組(3組)患兒BNP分別為16.05(40.7)pg/ml、12.40(47.1)pg/ml,7.45(33.6) pg/ml。術(shù)前3組BNP組間比較P=0.469P0.05。手術(shù)前患兒3組BNP值組間無差異(Table3)。 2.3先心病組3組患兒4個(gè)時(shí)間點(diǎn)組間BNP比較 2.3.1房間隔缺損組(1組)患兒4個(gè)時(shí)間點(diǎn)BNP值分別是16.05(40.7)pg/ml、135.5(90)pg/ml、113(79)pg/ml、72.3(55)pg/ml;室間隔缺損組(2組)患兒4個(gè)時(shí)間點(diǎn)BNP值分別是12.4(47.1)pg/ml、281(373)pg/ml、181(214)pg/ml、147(139)pg/ml;法洛氏四聯(lián)癥組(3組)患兒4個(gè)時(shí)間點(diǎn)BNP值分別是7.45(33.6)pg/ml、312(572)pg/ml、436(554)pg/ml、289(531)pg/ml;3組先心病患兒BNP術(shù)前術(shù)后共4個(gè)時(shí)間點(diǎn)組間變化有統(tǒng)計(jì)學(xué)意義,df為2,F值為5.414,P=0.006,P0.05。 2.3.2第3組患兒的術(shù)后BNP升高最明顯,下降較慢,術(shù)后第7天仍明顯高于前兩組,第1組術(shù)后BNP升高幅度較小,下降較快,術(shù)后第7天BNP值最低,第2組介于二者之間(Fig.3)。 2.4不同時(shí)間點(diǎn)之間的BNP比較 先心病組術(shù)前BNP為10.30(40.7) pg/ml,術(shù)后1天BNP為266(330)pg/ml,術(shù)后2天BNP為175(213) pg/ml,術(shù)后7天BNP為141(148) pg/ml。 2.4.1術(shù)后3個(gè)時(shí)間點(diǎn)與術(shù)前BNP比較 術(shù)后1天與術(shù)前BNP比較Z=-7.830P=0.000,術(shù)后2天與術(shù)前BNP比較Z=-7.314P=0.000,術(shù)后7天與術(shù)前BNP比較Z=-7.174P=0.000,P值均0.05,差異有統(tǒng)計(jì)學(xué)意義(Table4)。 2.4.2術(shù)后3個(gè)時(shí)間點(diǎn)互相比較 術(shù)后2天與術(shù)后1天BNP比較Z=-4.230P=0.000,術(shù)后7天與術(shù)后1天BNP比較Z=-6.317P=0.000,術(shù)后7天與術(shù)后2天BNP比較Z=-4.378P=0.000,以上P值均0.05,有統(tǒng)計(jì)學(xué)意義(Table4)。 2.4.3BNP值呈動(dòng)態(tài)變化,術(shù)后1天升高達(dá)峰值,術(shù)后第2天開始下降,術(shù)后7天血漿BNP值繼續(xù)下降,但未達(dá)術(shù)前水平(Fig.4)。 結(jié)論: 1不同先心病類型的患兒之間心功能指標(biāo)-血循環(huán)BNP沒有差別,但與健康兒童不同,這表明即使先心病患兒無心衰表現(xiàn),其心功能也較健康兒童為差。這與其畸形病理類型無直接關(guān)系,為疾病本身存在血流動(dòng)力學(xué)異常所致。 2先心病治療手術(shù)本身會(huì)對心肌產(chǎn)生一過性損傷。監(jiān)測BNP變化可早期防、早期診斷和早期治療先心病術(shù)后心功能異常。 3不同病理類型先心病,術(shù)后心功能變化不同。觀察術(shù)后血漿BNP變化,導(dǎo)抗心衰藥物的具體應(yīng)用療程。 4直到術(shù)后7天,BNP尚未恢復(fù)到術(shù)前水平,,表明患兒心功能還存在異常,仍需長期應(yīng)用口服強(qiáng)心藥。
[Abstract]:Objective: to determine the repair of congenital heart disease in children in operation or deformity of blood circulation of brain natriuretic peptide (Brain natriuretic peptide, through the dynamic change of BNP), understand the children with congenital heart disease or deformity correction surgery repair effect on cardiac function, so as to grasp the situation of functional recovery after surgery, early diagnosis, early treatment of children with abnormal heart function.
Methods: 1. prospective study, in our hospital from March 2010 to March 2011 the implementation of general anesthesia by extracorporeal circulation thoracotomy for repair of pediatric congenital heart disease and deformity correction surgery with 87 cases as the research object; at the same time outpatient medical examination of 26 cases of healthy children as healthy control group.2. according to the type of congenital heart disease, divided into 3 a sub group, septal defect group room, ventricular septal defect, tetralogy of Fallot group. And the study of the gender, age, body weight and surgical treatment, postoperative medication name, postoperative hospitalization time for registration. The control group were also recorded age, sex, weight, preoperative BNP value acquisition.3. time for 1 days before operation by hand venous blood in children with 2ml, into EDTA tubes, detection after mixing the standard amount of whole blood BNP, 1 days, 2 days after operation, the same 7 days by the person taking venous blood of children with 2ml, into EDTA anticoagulant tube after preservation for inspection Measuring, recording value. Healthy children collected BNP time for physical examination on the acquisition, with the former method. BNP immunofluorescence dry quantitative method for statistical analysis of data was determined using SPSS13.0.4. statistical software. The statistical test to test the level of a =0.05.
